Healthy Aging Cancer Prevention through Detection Early detection of colorectal cancer is the key to survival. Diet Makes a Difference Death rates are low for patients whose colorectal cancer is detected at an early localized stage; about 9% die within The Centers for Disease Control and Prevention notes that 5 years. Death rates are much higher, however, when the only about 27% of people age 65 and older eat five or more diagnosis occurs at an advanced stage; about 92% die servings of fresh fruit and vegetables each day. Screening remains underused even though in fruits and vegetables reduces the risk of many diseases, its benefits seem clear. Regular screening should be done including colorectal cancer, diabetes, hypertension, and for adults age 50 years and over.
